PWA with offline support / sync later


I’m about to start a new project and need to know if the requested features are possible with Ionic.

Basic description:
A service where users can create, read, update and delete items (with some sort of forms).
Image upload is also requested.


  • Service is available / accessible on all desktop platforms (macOS or Windows)
  • Service can be used online or offline with CRUD (create, read, update, delete) operations
  • Service uses some sort of database
  • If the user gets offline, he should be able to see the the latest state (when he was online for the last time)
  • The user should be able to add / delete / update items offline. This data should be synced (automatically or manually, does not really matter) as soon as he gets online later

Is that possible by using Ionic?
I guess creating a PWA would make sense here, maybe with some sort of Firebase backend?
Do you recommend a specific setup for this use case?

Thank you in advance for any suggestions!

U can create offline support with state and local database. Refer below articles for example and procedure
